I spent some time looking at this. It turns out that solution mostly works,
however using comment characters for line ends also works. E.G:
    #!/bin/sh<CR><LF>
    echo "This script works"   #<CR><LF>
    echo "without causing any" #<CR><LF>
    echo "errors in Bash."     #<CR><LF>

Considering this, I tried writing a top-level bash script of the form:
    #!/bin/sh<CR><LF>
    mount -t "$(cygpath -aw .)" "$(cygpath -au .)"  #<CR><LF>
    ./crlf_scipt.sh                                 #<CR><LF>
    umount "$(cygpath -au .)"                       #<CR><LF>

The problem I'm finding now is that for the context of ./crlf_script.sh
(when executed from /cygdrive/c/junk) my mount points are:
    c:\cygwin\bin on /usr/bin type system (binmode)
    c:\cygwin\lib on /usr/lib type system (binmode)
    c:\cygwin on / type system (binmode)
    c:\junk on /cygdrive/c/junk type system (textmode)   <----
    c: on /cygdrive/c type system (binmode,noumount)
    d: on /cygdrive/d type system (binmode,noumount)

So all looks good, my current directory is mounted as textmode.
Unfortunately my crlf_script.sh is still executed with no textmode
translation. I'm guessing it's hitting the /cygdrive/c mount and
deducing binary before seeing /cygdrive/c/junk.

Any ideas?
